两效溴化锂吸收式制冷机的运行性能 ,很大程度取决于外界参数 ,主要有蒸发器出口冷媒水温度和流量 ;吸收器 (或冷凝器 )进口冷却水的温度和流量 ;热源温度及冷却水、冷媒水的水质等。一般来说 ,制冷量越大 ,热力系数越高 ,蒸汽单耗越低 ,机组的性能也就越好 ,反之亦然。1 .冷媒 The operating performance of the two-effect lithium bromide absorption chillers largely depends on the external parameters, mainly the temperature and flow of the refrigerant water at the outlet of the evaporator, the temperature and flow rate of the inlet cooling water of the absorber (or the condenser), the temperature of the heat source and the cooling water , Water quality of refrigerant water and so on. In general, the greater the cooling capacity, the higher the thermal coefficient, the lower the steam consumption, the better the performance of the unit, and vice versa. 1 refrigerant
